All the threads I've read don't seem to help on my particular problem.
I've not been able to use my upload function in wordpress.
My permissions are wp-content: 777 and my directory uploads: 777.
I changed these permissions on my server control panel.
here is the error I get: -
'The uploaded file could not be moved to /home/mysite/public_html/wp-content/uploads.
Warning: Cannot modify header information - headers already sent by (output started at /home/mysite/public_html/wp-admin/admin-functions.php:1879) in /home/mysite/public_html/wp-includes/functions.php on line 1219'
